Greenhouse gases in our atmosphere trap heat, warm our atmosphere and keep our Earth at a comfortable 15 degrees. Extra greenhouse gases are released when we dig up and burn fossil fuels. We mostly do this to generate energy for industry, our homes and schools. Burning fuel to transport us and our stuff around the place creates more greenhouse gas. Deforestation, burping and farting cows are also large contributors. These gases put more energy into our atmosphere and are starting to affect our climate with more intense weather events and increased temperatures.

G20 summit: Barack Obama puts climate change at fore in speech at University of Queensland
In November 2014, Brisbane hosted the Group of Twenty (G20) Leaders' Summit, the principal forum for international economic cooperation and decision-making. Over the days of the event, Brisbane was in the global spotlight, with leaders from the world's most influential economies gathering in our city. Climate change was not included as a subject for discussion at the summit; Australian Prime Minister Tony Abbott stated he did not want the agenda "cluttered" by subjects that would distract from economic growth. Officials from the European Union and United States of America were reported to be unhappy with this decision.[11] At each of the previous summits climate change was included on the agenda.[12]
US president Barack Obama spoke at the University of Queensland during the G20 summit on wide-ranging topics, including announcing a $US3 billion contribution to an international fund to help poor countries cope with the effect of climate change.
US President Barack Obama has placed climate change at the forefront of the G20 summit in Brisbane, announcing a $US3 billion contribution to the Green Climate Fund, and calling on young Australians to pressure politicians to resist vested interests and tackle global warming.
A few hours later, Mr Obama was applauded every time he mentioned climate change in his speech at the University of Queensland. He warned that no region in the globe had more at stake than the Asia-Pacific and said climate change meant more bushfires, flooding, extreme storms and rising seas in Australia.
"The incredible natural glory of the Great Barrier Reef is threatened," Mr Obama warned.
The President said he wanted to return to Australia to visit the reef with his daughters when he had more time. "And I want them to be able to bring their daughters or sons to visit and I want that there 50 years from now," he said to applause.
As foreshadowed, he pledged $US3 billion to the Green Climate Fund to help developing nations adapt to cleaner-fuelled economies.
"Let them leap frog some of the dirty industries that powered our development, go straight to a clean-energy economy that allows them to grow, create jobs and at the same time reduce their carbon pollution," he said.
And he directly pleaded with Australia's youth to "keep raising their voices" and challenge "entrenched interests".
"It is in the nature of the world that those of us who start getting grey hair are a little set in our ways. That interests are entrenched. Not because people are bad people, it's just that's how we've been doing things and we make investments and companies start depending on certain energy sources and change is uncomfortable and difficult," he said.
"And that's why it's so important for the next generation to step in and say 'it doesn't have to be this way'," he said.

Ocean Acidification by the Alliance for Climate Education
Learn about how climate change is impacting our oceans. The Alliance for Climate Education is the nation's leader in climate science education and we're excited to present this short on ocean acidification.
Two years ago the Climate Commission warned that 2011-2020 is the ‘Critical Decade’ for tackling climate change. In particular, this is the Critical Decade for turning around rising emissions of greenhouse gases and putting us on the pathway to stabilising the climate system.
Energy is the ability to make changes or the capacity to do work. Energy appears in many different forms including kinetic (movement), potential (stored energy), gravitational, light, heat, chemical, elastic and electrical.
The Sun is the source of all energy on Earth. The energy from the sun comes in the form of light and heat. Plants are able to convert the light energy from the sun into a form of energy they can use to grow, move, repair their cells andreproduce.The basic unit of energy is the joule. To give you an idea of this unit, one joule is enough energy to lift a 1 kg weight to a height of 10 cm. Power is the rate at which energy is used and the unit is a watt.
Energy can change from one form to another: this process is called energy transformation. No energy transformation is 100% efficient and often heat energy is produced as the by-product. For example, a light globe transforms electrical energy into light energy (useful) and heat energy (by-product).
Humans focus a lot on electrical energy because we require it so frequently in our everyday lives. In Australia, we make most of our electrical energy from coal. There are many problems associated with the generation of electricity in a coal power plant. One problem is that when coal is combusted it produces a large amount of the greenhouse gas carbon dioxide. Another problem is that coal power plants are not very energy efficient and on average only 30 - 40% of the chemical energy in coal is converted to useful energy - the rest is lost as heat in the conversion process. Coal is also a fossil fuel, meaning that it is formed from 'dead things' over millions and millions of years. It is non-renewable, meaning that we will eventually run out! Renewable energy is derived from sources that can be replenished within the time of humancivilisation. Some of these sources include: solar, wind, hydro-electric, geothermal and biogas. A combination of these sources needs to be part of our energy plan to ensure a sustainable future.
We are constantly using energy. We use it to power machines, cars and other transport. We use it to heat and cool our homes. And we use it to produce electricity for lights and other appliances in our homes, schools and businesses. We use more and more energy in our daily lives. In the last hundred years our energy use has more than doubled. People use more electricity, travel more, and use hundreds of appliances that make our lives easier. But where does all this energy come from? Most energy we use comes from burning fossil fuels, such ascoal, oil and gas. The rest of the energy we use around the world comes fromnuclear reactors andhydroelectric power, or from other renewable energysources, like the wind and the sun.
Watch these 2 slide shows. Use the first presentation to find out more about renewable and non-renewable energy sources and how we can take personal action to reduce our usage. What is energy? Why is our society so reliant on fossil fuel energy? How can we save energy?
The second presentation focuses on Indiaand how they can take personal action to reduce their usage.

These services are defined as household access to electricity and clean cooking facilities (source). The absence of these services acts as a fundamental barrier to human well-being and to economic development. Globally there are over 1.3 billion people without access to electricity, 306 million of which are in India alone. Despite rapid economic development and ongoing energy access programs, this still represents a staggering 25% of India’s population (source).

WHAT IS ENERGY POVERTY?
Energy poverty is a lack of access to modern energy services.
These services are defined as household access to electricity and clean cooking facilities (source).
